2 claims. l

This invention relates to a calendar and has as its primary object provision of a weekly calendar which is adapted tobe adjusted to conform to the particular date of the days of the month applicable to the days of the week displayed on the calendar.

. A particular object of the invention is to provide adjustment means for compensating for the diierence in the numbers of days in the Various months so that a correct daily reading may be had of weeks embracing the last day or days of one month and the first day or days of a succeeding month.

A further object is to provide a calendar of the above character in which the parts are so formed and arranged as to be economically constructed and assembled.

With the foregoing objects in view, together with such other objects and advantages as may subsequently appear, the invention resides in the parts and in the combination, construction and arrangement of parts hereinafter described and claimed, and illustrated by way of example in the accompanying drawing, in which:

Fig. 1 is a view of the calendar as seen in front elevation;

Fig. 2 is a detail in horizontal section taken on the line 2 2 of Fig. l;

Fig. 3 is a view in side elevation;

Fig. 4 is a View in front elevation of a fragmentary portion of the date ribbon showing the date adjusting means in one position thereon;

Fig. 5 is a view similar to Fig. 4 showing the date adjusting means in another of its positions;

Fig. 6 is an enlarged sectional view and perspective taken on the line 6-6 of Fig. 5 depicting the construction of the date adjusting means.

Generally this invention consists of a calendar including a panel bearing the names of the days of the week arranged in a column together with a ribbon bearing the numbers of the days of the month arranged so as to be associated with the day column, and including means for winding the ribbonto position a selected group of numbers in such relation to the names of the days of the week as to be readable therewith in designating a week of dates.

Referring to the drawings more specifically, A indicates generally a panel on which is arranged the names of the days of a week disposed in a column in their consecutive Order commencing with Sunday and reading downwardly and ending in Saturday as shown in Fig. l. The panelA is formed with vertically spaced openings 'l and 8 and turnably mounted on the panel and extending transversely thereof across the openings 1 and 8 are spindles S and l0 on which are wound and secured the end portions of a ribbon B a portion of which overlies the outer face of the panel A alongside and parallel to the lcolumn of the designated days of the week.

As a means for journalling the spindles 9 and' l0 on the panel A, the latter is provided with a backing sheet i3 formed with bends i3 to overlie the spindles 9 and i0 and form bearings for the latter; the backing sheet I3 being suitably fastened to the back portion of the panel as by means of an adhesive and in a fashion to maintain the spindles 9 and l0 in place.

The ribbon B is formed in two sections C and D, the section C bearing on its outer face a column of numbers representing the days of a month from l to 31 inclusive, and the section D which connects with the length of ribbon C bearing on its face a series of numerals commencing with the numeral l. This second section of ribbon D carries any desired numbers in numerical order but preferably carries not more than six of such numbers since the purpose of this second section of ribbon is to provide at least one date following the last day of the month indicated on the leading length of the ribbon.

The numbers are spaced on the ribbon so that when a number is aligned with one of the designations of the day of the week on the panel A the remaining exposed numbers will align with the other designations of the days of the week as indicated in Fig. 1.

The above recited structure constitutes a weekly calendar since on manipulating the ribbon by winding it from one spindle to the other a number corresponding to a particular date falling on Sunday, on being positioned opposite the word Sunday the dates of the remaining days of the week will be indicated in their order.

As a means for rendering the calendar readable throughout a particular month, the panel A is fitted with a series of superimposed flexible strips E which strips bear the names of the months of the year, together with a designa- Ytion' of the number of days in the indicated Vin the provision of a means Yfor adjusting the leading portion C of the ribbon B so thatV the last date indicated on the leading section will correspond to the number of days of a month indicated on a strip E. Normally the last number on the leading portion C of the ribbon will be 3| as shown in Fig. 4 to accommodate the rib- -bon to the months containing thirty-one days, namely, January, March, May, July, August, October and December. In order to shorten the exposed area of the leading ribbon section C, a take-up F is provided embodying a slide I4 having apail` of" paralisi slots a and b separated by a bar c; the slots a and b being anked by side bars d and c. The take-up F also includes a link I5 having parallel side bars f and g. The outer end portion of the lead ribbon section C is passed through the slots d and b of the slide F to overlie the bar c, and underliethe bars d and e and is then passed4 through the link I5A around the bar f, then returned upon itself as `shown in Fig. 6, the end of the ribbon being attached to the bar c of the slide lli as indicated at I'Gf. The outer end of the other ribbon: section D isf affixed to the bar c' of the link I5 as shown in Fig. Gf at i2.,

In order to? facilitate Winding the members iii and I5 into the roll. formed by the ribbon, such members are made quite thin and as small as practicable :and: are aso curved in the direction of the length of the-ribbon so as to conform to the curvature of'the portion of the ribbon windings engaged thereby.

When it is desired to vary the length of the lead ribbon sectionL C the ribbon B is unwound from the spindles 9` and I E' to expose the members I4 and I5r and the member is is shifted lengthwise on. the:- ribbon to bring the desired number thereon contiguous: to the, member l5; the por'VH tion: of the ribbon taken up or fed out passes through the member' I5. In this fashion thev dates on the-ribbon may be terminated according to the last day or the number. of days in the month'se'- lected. For example, the ribbon may be taken up to conceal' the date numbers 29, 30' and 3i and expose the number 2-8 next to thelink I5 to designate the number ofl days in February, or tozexpose the number. 29 as shown in Fig. das -when February has twenty-ninerdays in leapV year. In like fashion the last number may be 30 in accordance with the number of days in April, June, September andNovember..

In the operation of the invention, having selected the particular month' and week of the month to be indicated on the calendar', the datebearingl ribbon. is adjusted las above described to indicate at the end of the iirst ribbon section C the number of days of the selected month, whereupon the spindles 9 :and I9V are manipulated to wind the ribbon to a positionwhere. the exposed group of numbers thereon will align with the namesof the days of the weekA according to the datesthe'reof'. In the example4 shown in the dra-wings, the month of January has been selected which has thirty-one.V days, in which instance the numbered ribbon will be adjusted so that the-rst section C thereof will' end in thev number 3| Vas shown in Fig. 4. Assuming'v thatthe first day of January falls on Sunday the ribbon will then be` This operation is repeated until the last week in the month which in the examples given Would occur on the 29th. The calendar vwould then read Sunday-29; Monday- 30; Tuesday-31. The number l on the second section D of the ribbon `would then align with the word Wednesday to designate the first of the succeeding month of February. When this date is reached it is desirable to4 adjust the length. of the ribbon Yaccording to the number of days in February so that the last date will appear immediately before the number l on the second section of the ribbon. On this adjustment being completed the ribbon is rewound on the spindle I0 until the number 1 on the first section thereof is opposite or in line Vwith theword Wednesday When the calendar is changed according to changes in the month, the proper strip E is placed outermost in the stack thereof into position to be read from' thef front, of the calendar. By provisioiroithe data on the month designating strips a person'l not knowing the number of days in a particular month can. be advised thereof on referring to the'data onthe strips.

I claim:

1-. In a calendar, a ribbon embodying a first section carrying a row of numbers from l toY 31 inclusive, and a second sectionA bearing at least the numeral 1; a link to Vwhich the second section isA attached contiguous the number 1 thereon and through which an end` portion of the rst section is looped to formalooped end-a slide on the first section slidable thereon to which the loop end ofthe first section'is aixed, apair of spaced spindles bearing said ribbon onwhich the-ribbon may be Wound from eitherl spindle, a panel, means forA turnably supporting said spindles on said panel in spacedI relationto eachV other with a length of said ribbon overlying the front of said panel, and indicia on said panelV designating the days cf 'the-week with whichexposed numbers on said. ribbon may bealigned.

2. In a calendar, apanel bearing the names of the days of the. week, a ribbon provided with a row of numerals representing the days of the month, a pair of spaced spindles journalled on said panel on which spindles said ribbon, is mounted to be wound from either spindle to the other, said ribbon being positioned relative to the names of the days of the Vweek on the panel to align a group of thenumbers thereon in numerical order in line with the designated days of the week, said ribbon being formed in two sections with the numbers on one of said sections reading from l to 3,1 inclusive, the second section being connected to the irst section` and bearing at least the number l arranged contiguous and spaced from theV numberr 31 on the other section; and take-up means including the connection between the two ribbon sections whereby th first ribbon section may be; adjusted to varyV the' number exposed at the endV portion thereof contiguous the number l of the other section.
